Figure 6

The relative cumulative frequency of agent’s prejudice levels by trait, in a population of 100 agents and two traits. Pi = 0.5 and Si = 0.5 are fixed for all agents, with simulations carried out using 50,000 generations. Initially all agents i have αi = 0. The circles represent the relative proportions of agents with those particular characteristics, accumulated over ten randomly seeded runs (see (b) and (d)). Two alternative starting configurations are employed: an equal split between sub-populations (see (a)) and a 90/10 imbalance between sub-populations (see (c)).
